简要总结
The investigators plan a prospective cross-sectional study of pediatric and adult healthy volunteers and patients with chronic kidney disease that will correlate a variety of quantitative MRI biomarkers with severity of renal insufficiency and available histopathology. Over 3 years, the investigators will recruit approximately 20 healthy volunteers, 20 patients with chronic kidney disease (CKD) Stage 2-5, and 20 patients with renal transplant kidneys. The investigators also plan to assess the effect of inflammation on the quantitative MRI biomarkers by recruiting approximately 20 additional patients with active lupus nephritis.

入选标准
- •Subjects who meet all of the following criteria will be eligible for the study:
- •≥ 10 and ≤ 25 years of age and;
- •Kidney transplant patients, who have had a recent kidney biopsy (within 1 year) that shows interstitial fibrosis OR
- •Patients with CKD Stage 2-5 who have previously had a biopsy (within 1 year) OR
